What AMP Clean Energy does

AMP Clean Energy (legal entity: Aggregated Micro Power Holdings Limited) is a privately-held UK distributed energy company founded in 2006 and headquartered in London. The company develops, funds, owns, and operates low-carbon energy assets on customers' sites, with a portfolio of approximately 225 assets across heat decarbonisation (111 MW of biomass and electric boiler capacity in operation), grid flexibility (167 MW of flexible generation operational and in build, plus 90 MWh of battery energy storage in build), and downstream biomass fuel supply. Customers span industrial manufacturers (Simpsons Malt, Muntons, Bunnahabhain Distillery, Sunseeker International), commercial and institutional sites (schools, care homes, golf clubs, heritage sites including Norwich Cathedral and Skibo Castle), and public-sector / local-authority partners hosting Battery Box and Urban Reserve assets for National Grid balancing services.

The business model is a fully-funded, zero-upfront-capex "energy-as-a-service" structure. AMP finances and installs the on-site generation or storage asset, then delivers energy (or grid services) to the customer under long-term energy supply agreements of approximately 20 years, with customers paying per kWh of heat delivered or via capacity-market and balancing-mechanism revenues for grid-flexibility assets. Vertically integrated revenue streams include: subscription-style ESAs, recurring service and maintenance contracts (with 24/7 monitoring and HETAS-certified engineers), biomass fuel supply (Woodsure-certified wood chip and ENplus A1 wood pellet, sourced on average within 50 miles of each site), boiler buybacks of third-party biomass assets, and usage-based grid flexibility revenue from battery storage and flexible generation. Distribution is direct enterprise field sales only — no channel partners — targeting engineering, finance, procurement, and legal stakeholders at industrial and commercial customers.

Growth is being capitalised by a £50 million institutional round from the National Wealth Fund and Asterion in August 2025, alongside refinancing of up to £250 million of 8% Senior Secured Loan Notes via Aggregated Micro Power Infrastructure 2 Plc. The operating footprint spans six UK office locations (London, Hooton, Telford, Fort William, Glasgow, Stirling), with two wholly-owned operating subsidiaries — AMP Biomass Fuel Ltd and AMP Clean Energy Services Limited — and a leadership team led by CEO Mark Tarry, with Group COO Bruno Berardelli and Group HSEQ Manager Mark Close. Verified outcomes across the installed base include 60,000+ tonnes of customer CO2 saved per year, with flagship projects such as Bunnahabhain Distillery (95% emissions reduction versus oil, net zero 15 years ahead of the Scotch Whisky Association target) and Simpsons Malt's Tweed Valley Maltings (UK's first e-boiler for malting, displacing over 140 GWh of fossil fuel annually).

Revenue model

1. Long-Term Energy Supply Agreements: AMP develops, funds, and operates low-carbon energy centres, selling low carbon energy back to customers under long-term energy supply agreements (typically 20 years). Customers pay for heat on a per kWh basis with no upfront capital required. The company bears operational risk on system performance.
2. Biomass Fuel Supply: Supply of wood pellet and wood chip biomass fuel to customers, including those with AMP-installed systems as well as third-party biomass boiler owners. Revenue from fuel delivery and supply agreements.
3. Service and Maintenance Contracts: Ongoing servicing, maintenance, and remote monitoring of biomass boilers and energy systems. Includes 24-hour call-out support and telephone assistance for customers on service contracts.
4. Boiler Buyback Deals: AMP purchases existing biomass boilers from customers, taking over ownership and management. Customers benefit from expert service and maintenance while AMP generates revenue through ongoing energy supply contracts.
5. Grid Flexibility Services: Battery energy storage systems and flexible generation assets provide grid stability services to National Grid, earning revenue through capacity payments and flexibility market participation.

Core offering

AMP Clean Energy is a UK distributed energy company that develops, funds, operates and services low-carbon energy production assets — including biomass boilers, high-voltage electric boilers, battery energy storage systems and flexible generation plants — and delivers the resulting heat, power and grid balancing services to industrial, commercial and public sector customers under long-term energy supply agreements with no upfront capital required from the customer.

Product overview

AMP Clean Energy operates as a distributed energy company offering three interconnected service pillars: Heat Decarbonisation (biomass boilers, electric boilers, and related systems for industrial and commercial decarbonisation), Grid Flexibility (Battery Box, Urban Reserve, and battery storage services for network balancing), and Energy Services (biomass servicing, maintenance, fuel supply, and boiler buyback programmes). The company develops, funds, and operates low-carbon energy assets across the UK, providing customers with zero-capex solutions through long-term energy supply agreements. Core products include Biomass Boiler Systems, the Battery Box grid storage product, and Urban Reserve flexibility assets, supported by a nationwide fuel supply business delivering certified wood pellet and wood chip.

Direct peers

• Vital Energi: UK-based decentralised energy and CHP specialist providing district heating, biomass, and energy centres under long-term supply agreements. Directly comparable to AMP in business model, technology mix, and industrial customer focus — AMP partnered with Vital Energi on the Muntons decarbonisation project.
• Rendesco: UK developer and operator of low-carbon district heating schemes using ground source heat pumps, water source heat pumps, and waste heat recovery. Comparable to AMP's heat decarbonisation pillar and long-term supply agreement model, though with a different technology mix.

Emerging players

• Hemiko: UK low-carbon heat network developer developing and operating large-scale heat networks and energy centres using a developer-funded model. Comparable to AMP in targeting industrial and commercial heat decarbonisation with shared risk/revenue structures, though focused more on heat networks than individual site biomass.
• Harmony Energy: UK battery energy storage developer and operator with multi-GWh pipeline. Comparable to AMP's Battery Box and grid flexibility business in providing BESS-driven flexibility services to National Grid, though pure-play focused on storage rather than heat.

Broad incumbents

• Equans UK & Ireland: Major UK energy services and facilities management provider (formerly ENGIE's services arm) offering district heating, CHP, and energy centre solutions. Comparable to AMP in heat decarbonisation scope but operates across a much wider portfolio including FM services.
• Veolia UK: UK arm of global environmental services group operating district heating networks (e.g., Nottingham, Belfast) and biomass/waste-to-energy facilities. Comparable to AMP in biomass CHP and grid-flexibility-adjacent services, though much larger and diversified.
• SSE plc: Major UK utility with significant renewable generation, flexible thermal generation, and district heating operations (e.g., Southampton, Oxford). Comparable to AMP in CHP/biomass generation and grid balancing assets, though operating at much larger scale with diversified business.
• ENGIE UK: Global energy giant with significant UK presence in decentralised energy, biomass CHP, and district heating. Comparable to AMP across all three pillars (heat, flexibility, services), with much larger balance sheet and pan-European reach.
• Drax Group: UK's largest biomass power generator and one of Europe's largest decarbonisation projects. Comparable to AMP in biomass generation technology and fuel sourcing, though operates utility-scale rather than distributed industrial heat — competes in similar fuel markets.
• Centrica Business Solutions: UK energy company offering industrial heat decarbonisation, CHP, and energy services to commercial and industrial customers. Comparable to AMP's heat decarbonisation and energy services pillars, with much larger balance sheet and broader energy retail/marketing capabilities.
